'eh, say wha? I haven't heard of this before. Are people having to move the electric fuel pump? How many have had these problems?RV9inIowa wrote: I can't remember if you are building a NW or TD, but if NW, then go ahead and move that fuel pump now. If you don't, later on you'll find out that the nutplate interfers with the engine mount
Sure, kick a guy while he is happy. I figure I have few thousand left to set. Oh well, your not going to pop my bubble that easily.Looks great, but you still have a few rivets to set

No, I am not even counting hours. It is what it is.

Every 7A or 9A will have the problem - the deisgn is such that the engine mount tube pressed on one of the nutplatest that holds the fuel pump on. Well documented problem. Some people grind the nutplate, some (like me) shorten the bolt, add washers to the engine mount, some move the fuel pump. If I was building again I'd move the fuel pump up a bit.Spike wrote:RV9inIowa wrote: 'eh, say wha? I haven't heard of this before. Are people having to move the electric fuel pump?

I don't remember... are you going with a carburetor or fuel injection? If you're doing fuel injection, you'll likely have a fuel pump inside the cabin below the fuel selector valve and this won't be an issue.
Anyways, NICE WORK! I'll never forget the day we flipped the fuse. It's a milestone you worked hard for and you deserve all the warm fuzzies you get. Now the emphasis shifts from building a fuselage to putting things inside it.
Congrats!

I am building a Carbed version. Ill just deal with it down the road with a file or bolt. I really dont want to penetrate the firewall again if I don't have to. I want as few holes as possible.
Thanx for the heads up though!

Actually I am working on it, pretty diligently too. I am just having problems finding the time to upload photos, etc. I'll try to get something up shortly.
